highly significantp < 0.005
In the ICAN data, Spearman correlational analyses between age and TBR for all permutations showed highly significant correlations (all Cz p < 0.005 unless stated otherwise), as expected, with the strongest correlations for the Session-based averaging method ( r = − 0.28; df = 234) followed by Welch (Hann) ( r = − 0.27; df = 234) and the weakest correlation for Trial based ( r = − 0.26; df = 234).
